A digital geochronological index to act as a domain constraint for geochronology columns in corporate data tables. It decodes geochronology codes, models pseudo parent-child relationships between intervals (for example, find the epochs within a given period), allows range searches (for example, find the epochs between lower limiting and upper limiting epochs) and provides radiometric ages with ranges of uncertainty. Follows the recommendations of the BGS Stratigraphy Committee. Phanerozoic after Gradstein and Ogg (1996), with the Ordovician scheme of Fortey et al. (1995); Proterozoic after Cowie and Bassett (1989); Archaean after an unpublished decision of the Precambrian Subcommission of the IUGS. Covers the whole of geological time. Geochronological resolution usually to age level. Lower resolution in the Archaean, Proterozoic, Cambrian. Greater resolution in the Caradoc Epoch.

The data comprises information on the subsurface structure of stratigraphic levels and units in the United Kingdom, detailing depth to and thickness of the units. These result from projects in different parts of the UK performed at different times. Common working scales are 1:50 000 and 1:250 000 with appropriate differences in detail. Much mapping results from interpretation of seismic data, and as a result many of the structural maps are in time rather than depth, although some have been depth converted.

Fault and Horizon interpretations are provided for the Offshore Corinth Rift. The majority of the interpretations were based on 2D profiles from seismic reflection surveys collected by the R/V Maurice-Ewing in 2003, M.V. Vassilios in 1996 and 2003, and the R/V AEGEAO. Interpreted faults include major rift border faults as well as minor syn-rift faulting. Interpreted horizons include basement, a basin wide unconformity and five inferred transgressive surfaces based on variations in seismic character. Details of the fault and stratigraphic framework can be found in Nixon et al. (2016). Rapid spatiotemporal variations in rift structure during development of the Corinth Rift, central Greece. Tectonics, 35, 1225-1248.’ Published paper, Nixon, C. W., et al.

The Nirex Digital Geoscience Database (NDGD) holds extensive sets of data describing geoscientific, geographical, hydrogeological and logistical aspects of the Sellafield area in western Cumbria region. Some datasets comprise unmodified field data (as collected, measured or observed in the field). Others include values assessed during laboratory analysis or testing. Derived or interpolated information, resulting from modelling activity or the integration of several datasets, also accounts for a significant portion of the NDGD holding. The data consists of mainly borehole derived information including Borehole location and survey information, Sample location information, Logistics, Geological, geophysical (including borehole geophysical logs) and geotechnical borehole Geology datasets and Hydrological, hydrogeological and hydrochemical borehole datasets (though information from the down-hole monitoring strings and most groundwater related information is not held in the NDGD). The NDGD holds all of the raw and processed digital data arising from the Nirex (Nuclear Industry Radioactive Waste Executive) Sellafield Geological investigations boreholes drilled during their investigation programme into the suitability of Sellafield as a site for the disposal of intermediate and long-lived low level radioactive waste between 1989 and 1997. The ownership of Nirex (Nuclear Industry Radioactive Waste Executive) was transferred from the nuclear industry to the UK Government departments DEFRA and DTI in April 2005, and then to the UK's Nuclear Decommissioning Authority (NDA) in November 2006.

Stratigraphic and ecological data from tidal marsh sites in south-central Chile. Includes stratigraphy, diatom assemblages and radiocarbon dates from fossil cores and diatom assemblages from modern tidal marsh samples. Data were collected to provide evidence for multiple great earthquakes in south-central Chile, and enable the reconstruction of vertical land-level changes associated with these earthquakes. Data are from tidal marsh sites within the 1960 earthquake rupture area along the Chilean subduction zone (37.5 - 46 degrees South).

Database of palaeontological specimens, world-wide coverage, including both "Museum" and "Survey" fossil collections from Keyworth and Edinburgh. Development commenced in Autumn 2000 and is ongoing. The database currently contains over 100,000 entries, including half of the taxonomic reference collection held at BGS Keyworth. Internet search access is available on the BGS web site. Key fields in the dataset, many of which can be searched for, include, sample number, nature of sample, confidentiality, collector/donator & year, register details, locality information (including grid reference, map sheet etc.), stratigraphy, type status, identifications & authority and publication details.

Reports, images, GIS and gridded products describing the Palaeozoic geology and conventional petroleum systems of parts of the UK offshore from the greater Irish Sea area. Carboniferous rocks were the focus in areas from the Firth of Clyde, Solway Basin, Manx-Peel Basin to the East Irish Sea Basin and surrounding areas (Quadrants 110-126). The peer-reviewed products were produced for the 21CXRM Palaeozoic Project by BGS for DECC/OGA, Oil and Gas UK and oil company sponsors between November 2014 and May 2016, to improve regional digital datasets and knowledge of the underexplored Palaeozoic petroleum systems, and to stimulate exploration. The petroleum systems analysis was based on new interpretations of well, seismic, gravity-magnetic and source rock datasets, integrated with petrophysical studies, basin modelling and UK onshore knowledge. Released data were collated and interpreted, and interpretations of unreleased data were included with agreement of the data owners. Unreleased raw data is excluded. The datasets are applicable for use at scales between 1: 750,000 to 1: 3,000,000.

A series of technical palaeontological and biostratigraphical reports produced in the London, Leeds, Edinburgh and Keyworth offices of BGS between 1953 and March 2000. The reports provide information on fossils collected during Geological Survey mapping or supplied by clients. Fossils are collected in order to date (relative age) the rocks in which they occur and/or to provide evidence for the conditions of deposition, so the information contained in each report usually includes determinations of the fossils present in a collection and an interpretation of their stratigraphical and/or their palaeoenvironmental/palaeogeographical significance.Individual reports vary enormously in scope, depending on the reasons for the investigation. Some reports may be site specific, documenting the fossil fauna/flora from a particular locality or borehole, whereas others may deal with material from a number of localities on a 1:10 000, 1:25 000 or 1:50 000 sheet, or from several boreholes. Other reports may be in the form of reviews. Geographical coverage is wide, covering the UK and Northern Ireland onshore, UK offshore and overseas localities.All reports are held as hardcopy only. Each report bears a unique identifying number in the form SS/YY/NN, where 'SS' identifies the series, 'YY' identifies the year in which it was written and 'NN' is a serial number. Reports were numbered sequentially, regardless of whether they dealt with material from the UK and Northern Ireland onshore, UK offshore, or overseas, and a sequential set is held by BGS. Reports are also filed by 1:50 000 sheet, (UK onshore), offshore quadrant and foreign country, as appropriate.

PALSLIDES_ED is the BGS Edinburgh Palaeontological Slides Collection. It comprises two registration series. The MIC (microfossils) series, which is added to sporadically, includes c.950 individually registered slides (each with up to 100 cells) of microfossils (mainly foraminifera and ostracods). The PS (Palaeontological thin Sections) registration series, which has not been added to since 1987, comprises 4202 fossil thin sections and mounted slides, and includes various donated collections. Both the MIC register (10 volumes) and PS register (2 volumes) record the locality of each slide and any previous registration numbers. Stratigraphic information may also be given. Taxonomic information is not complete. There is, at present, no separate index (either analogue or digital) to the dataset, but it is included in FOSSLOC4. GSE_SPECIMENS and SMITH_GSE include those slides and thin sections transferred to the Type and Stratigraphical Collection from the Survey and John Smith collections.

Stored in Murchison House, this dataset (FAUNGRAPHLOG_ED) is the BGS UK (North) collection of paper graphic logs from boreholes and measured natural sections, particularly in the Carboniferous of Scotland and northern England. Some 18000 of these records include hand written macrofossil occurrences and assemblages from certain (often subsequently interpreted) stratigraphical levels in the borehole or section. There is at present no separate index (either analogue or digital) to FAUNGRAPHLOG_ED but a pathway to it is FOSSLOC, the index to the Survey Collection of fossils from UK (North).
